ABSTRACT:
The invention is directed to a traveling trolley, in particular a single-rail trolley having a compact height. A traveling trolley constructed in accordance with the present invention includes a supporting frame with running wheels that run on the bottom flange of a rail, a hoist arranged at the supporting frame, a lever member arranged at the axle of the driven running wheel so as to swivel or pivot, and a friction wheel supported at the free end of the lever member via an additional axle. The friction wheel and the driven running wheel are each coupled to a respective toothed wheel and these toothed wheels are driven by a driving unit. A spring element arranged between the lever member and the supporting frame urges the friction wheel into contact with the bottom flange of the rail.
